Project Eleven says rapid quantum advances could expose Bitcoin wallets sooner than many expect.
Quantum computing risks may arrive faster than many in crypto expect. New research from Project Eleven argues that progress could accelerate suddenly after years of limited visible change. Concerns center on encryption systems that protect Bitcoin wallets and global digital infrastructure. Industry groups are already discussing migration plans before the threat becomes immediate.
Crypto Security Fears Rise as Researchers Warn of Abrupt Quantum Advances
Project Eleven released a report on Wednesday warning that “Q-Day” could arrive as early as 2030. Researchers at the post-quantum security startup believe a break of modern encryption is more likely than not by 2033. Their estimates place the event within a range of several years on either side.
Researchers argue that quantum development may not follow a steady timeline. Instead, hardware and algorithm improvements could stack together and trigger abrupt capability jumps. Project Eleven described the pattern as “nothing, and then all at once.”
Recent progress has added weight to those concerns. Last month, a researcher extracted a 15-bit elliptic curve key using quantum hardware. Current cryptocurrency systems still rely on far stronger 256-bit encryption, leaving a major gap before Bitcoin-level security is threatened.
Even so, Project Eleven estimates that nearly 6.9 million Bitcoins could be subject to quantum exposure under certain conditions. At current prices, that stash is worth more than $560 billion.
Dan Robinson Suggests Timestamp Proofs for Future Quantum-Safe Bitcoin Claims
Researchers also warned that migration timelines matter as much as technical readiness. Their report referenced Mosca’s inequality, a theory arguing that systems already fall behind if upgrades take longer than threats need to emerge.
Crypto developers have started discussing possible responses. One proposal from Paradigm researcher Dan Robinson would allow Bitcoin holders to prove wallet ownership today using timestamps. Those records could later support claims on quantum-safe versions of Bitcoin without exposing wallet activity on-chain.
Another proposal, BIP-361, backed by Jameson Lopp and other contributors, suggests a multi-year migration process toward quantum-resistant addresses.
Pressure is growing outside crypto as well. Google has already advanced its timeline and is targeting a transition to quantum-resistant cryptography by 2029.
